Deep Wizardy by Diane Duane
Yes its a kids book, but this comes a close to perfection as a book can get. Pepare to get in touch with your inner hippy.
Kit and Nita are newly made wizards. They are pitted against the evil lone power, the entity who intoduced death, and represents entropy, the eventual death of the universe. After blocking his purpose in the last book, Kit and Nita are taking some break time with their parents on a long island beach.
Enter hotshot the dolphin, crying with distress that a whale is wounded. Nita and Kit transform into whales and head off to save the whale from sharks. They discover that she too is a wizard, and that the magic she has to perform, "the song of the sea", is essential for the survival of not only whales, but humans too. The last time the magic failed, Atlantis sunk beneath the waves.
Twelve singers are required for the song, 11 whales, of which Nita and Kit are two, and the Pale Slayer, Master of sharks, ageless master of death.
The Pale slayer has to be one of the best charachters I have ever encountered in my reading. Its one of those cases where you wish you'd thought of it. I Hope I've given you enough to make you want to read this book, but not enough to spoil it.
Well done Diane. 9 out of 10.
